Description

Technical Field

[0001] This invention relates to the field of vehicle suspension system configuration technology, and more particularly to an integrated dryer bottle structure. Background Technology

[0002] Air suspension dryer bottles are used to remove moisture from compressed air, preventing water vapor from entering the air suspension system and avoiding corrosion, icing, pipe blockage, and air pump damage. Currently, the main structure of a dryer bottle consists of a shell, desiccant, and a one-way valve. It removes moisture from compressed air, ensuring the air circuit remains dry, effectively preventing problems such as air circuit icing and blockage, valve corrosion, and air pump stalling in winter. The technology of air suspension dryer bottles has evolved from an independent component to a deeply integrated key module.

[0003] For example, Chinese patent CN118793814A discloses a valve body with an integrated drying chamber, including a drying section and a mounting section, which are integrally formed. The mounting section is provided with pneumatic connection ports and electrical component connection ports. The pneumatic connection ports include an air inlet port, an exhaust port, an air tank port, an air spring port, an air compressor port, and an air compressor exhaust port. The drying section includes a drying chamber, and the mounting section is provided with an air inlet channel and an exhaust channel that communicate with the drying chamber. The air inlet channel communicates with the air compressor exhaust port, and the exhaust channel communicates with the air spring port. The drying chamber is provided with an opening and closing structure to limit whether the drying chamber is connected to the exhaust channel. The integration of the drying section and the mounting section makes the entire valve body structure more compact and effectively enhances the overall strength and stability of the valve body, reducing connection points and potential leakage points during assembly.

[0004] However, in the existing technology, although the valve body and the drying chamber are integrated, the structure is complex and the production cost is high. At the same time, in order to maintain the gas pressure, the gas in the drying chamber is usually saturated and difficult to be discharged, resulting in a short service life of the desiccant. Summary of the Invention

[0005] To address the above shortcomings, this invention provides an integrated drying bottle structure that can remove moisture from the drying bottle during exhaust. The specific technical solution is as follows: An integrated dryer bottle structure includes: a dryer bottle, an inner liner inside the dryer bottle, an air inlet on the lower side of the dryer bottle and the inner liner connected to a one-way valve, compressed gas entering the dryer bottle and the inner liner through the one-way valve, a gap between the dryer bottle and the inner liner, a first opening at the upper part of the inner liner passing through the upper part of the dryer bottle, the first opening being connected to a first connecting pipe, the first connecting pipe being connected to an actuator and a solenoid valve assembly, a second opening on the upper side of the dryer bottle, the second opening being connected to a constant pressure regulating unit, a passage between the solenoid valve assembly and the constant pressure regulating unit, and the constant pressure regulating unit being connected to the outside. The second passage pipe is connected to the constant pressure regulating unit, which includes a constant pressure plug for sealing the second opening. When the solenoid valve assembly is energized, the passage between the solenoid valve assembly and the constant pressure regulating unit is connected. The gas in the passage actuates the constant pressure regulating unit, pushing the constant pressure plug upward and separating it from the second opening. The second opening is connected to the second passage pipe. Furthermore, the gas in the actuator flows back, and the backflowing gas flows downward into the inner liner through the first opening. After being dried in the inner liner, it flows from the lower part of the inner liner into the gap, then enters the constant pressure regulating unit through the second opening, and is discharged through the second passage pipe.

[0006] Preferably, the inner liner is provided with pressure plates at both the upper and lower parts, and filter felts are assembled and connected to the inner sides of the two pressure plates. Desiccant is filled between the two filter felts. When high-pressure gas enters the inner liner, it passes through the pressure plates, filter felts, and desiccant in sequence, and then through the upper filter felt and pressure plates.

[0007] Preferably, the constant pressure regulating part includes a cylindrical shell integrally formed and connected to the drying bottle. The inner side of the cylindrical shell is slidably sealed with a constant pressure piston connected above the constant pressure plug. The middle part of the constant pressure piston is a cylindrical body with a cavity. A constant pressure spring is installed in the upper cavity of the constant pressure piston. The passage between the solenoid valve assembly and the constant pressure regulating part is located on the lower side of the upper cover of the constant pressure piston.

[0008] Preferably, a spring adjusting seat that cooperates with a constant pressure spring is installed on the upper part of the cylindrical housing. A constant pressure end cap is assembled and connected to the upper side of the spring adjusting seat. The upper part of the constant pressure spring is located in the cylindrical cavity of the spring adjusting seat. A component for adjusting the compression of the constant pressure spring is provided between the spring adjusting seat and the constant pressure end cap.

[0009] Preferably, the lower side of the constant pressure end cap is provided with a plurality of grooves of different depths, and the spring adjusting seat is provided with a protrusion that cooperates with the grooves. When the protrusion of the spring adjusting seat is located in different grooves, the spring adjusting seat compresses the constant pressure spring to different degrees, and the constant pressure end cap is fastened to the spring adjusting seat.

[0010] Preferably, the lower part of the cylindrical body of the constant pressure piston is provided with a through hole, which can connect the inner cavity of the cylindrical body with the second opening.

[0011] Preferably, the first opening of the drying bottle is connected to a quick-connect tubing connector, and the second opening is connected to a plastic connector, which is connected to the quick-connect tubing connector.

[0012] Preferably, a first sealing ring is connected between the constant pressure end cap and the cylindrical housing, a second sealing ring is connected between the spring adjusting seat and the constant pressure end cap, and a third sealing ring is used to seal the constant pressure piston and the cylindrical housing.

[0013] Preferably, the cylindrical shell has a sliding column located above the second opening, and the lower part of the cylindrical body is located inside the sliding column.

[0014] Preferably, the outer side of the cylindrical body is provided with a piston sealing ring that is slidably and sealingly connected to the sliding column, and the through hole at the lower part of the cylindrical body is located below the piston sealing ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention is ingeniously designed. The constant pressure plug of the constant pressure regulating part can not only serve as a pressure relief port for the drying bottle, but also separate from the second opening when the solenoid valve is opened, thereby allowing the gas in the drying bottle to be squeezed out by the gas in the actuator.

[0016] 2. The present invention has a simple structure. By cooperating with the spring adjustment seat and the constant pressure end cap, the compression of the constant pressure spring can be adjusted by different positions, thereby controlling the maximum air pressure in the air circuit. This allows the constant pressure plug on the constant pressure piston to be pushed after exceeding the safe air pressure, opening the pressure relief channel to release pressure and preventing the pressure from exceeding the safe air pressure.

[0017] 3. This invention integrates the drying bottle, inner liner, and solenoid valve assembly. The drying section dries the gas entering the actuator. Simultaneously, when the gas in the actuator flows back, some of the gas can flow back into the drying bottle. This allows the gas originally stored in the inner liner to reach the drying bottle from the bottom of the inner liner and then exit from the second outlet. This also removes the moisture originally stored in the inner liner. The dried gas remains in the inner liner, effectively extending the service life of the desiccant. Attached Figure Description

[0025] Reference Figures 1-5 An integrated dryer bottle structure includes: a dryer bottle 1, an inner liner 2 inside the dryer bottle 1, an air inlet on the lower side of the dryer bottle 1 and the inner liner 2 connected to a one-way valve, compressed gas entering the dryer bottle 1 and the inner liner 2 through the one-way valve, a first opening 21 passing through the upper part of the inner liner 2 through the upper part of the dryer bottle 1, the first opening 21 being connected to a first pipe 201, the first pipe 201 being connected to an actuator and a solenoid valve assembly 7, and a second opening 101 on the upper side of the dryer bottle 1. 01 is connected to a constant pressure regulating unit. A passage is provided between the solenoid valve assembly 7 and the constant pressure regulating unit. The constant pressure regulating unit is provided with a second pipe 801 that communicates with the outside. The constant pressure regulating unit includes a constant pressure plug 81 for sealing the second opening 101. When the solenoid valve assembly 7 is energized, the passage between the solenoid valve assembly 7 and the constant pressure regulating unit is connected. The gas through the passage causes the constant pressure regulating unit to operate, thereby separating the constant pressure plug 81 from the second opening 101, and connecting the second opening 101 with the second pipe 801.

[0026] In this embodiment, the upper part of the desiccant 1 is provided with a receiving cavity located outside the first opening 21. An inner O-ring 6 is connected between the receiving cavity and the first opening 21 to seal the gap between the first opening 21 and the inner O-ring 6. At the same time, the first connecting pipe 201 is integrally formed and connected to the desiccant 1, and the first connecting pipe 201 communicates with both the receiving cavity and the first opening 21. A gap is left between the desiccant 1 and the inner liner 2. Compressed air enters both the desiccant 1 and the inner liner 2 simultaneously through a one-way valve. The plug 81 seals the compressed air in the desiccant 1. Inside, the gap between the drying bottle 1 and the inner liner 2 is filled with compressed air. The compressed air in the inner liner 2 enters the actuator through the first opening 21, putting the actuator into operation. At this time, the solenoid valve assembly 7 is in the closed state. When the actuator needs to release gas, the solenoid valve assembly 7 is energized. It should be noted that before the solenoid valve assembly 7 is opened, the inner liner 2 and the drying bottle 1 are filled with compressed gas and are in a saturated state. When the solenoid valve assembly 7 is energized, the constant pressure regulating section is connected to the first opening 21, and the gas from the actuator can reach the constant pressure regulating section. Compressed gas acts on the plug 81 of the constant pressure regulating section, causing the plug 81 to move upward, opening the second opening 101, allowing the gas in the drying bottle 1 and the inner liner 2 to be discharged from the second opening 101. Simultaneously, the gas in the actuator flows back, passing through the first opening 21 and then downward into the inner liner 2. After being dried in the inner liner 2, the gas flows from the bottom of the inner liner 2 into the gap between the drying bottle 1 and the inner liner 2, then passes through the second opening 101, reaches the constant pressure regulating section, and is discharged from the second pipe 801 connected to the constant pressure regulating section. The inner liner 2 is equipped with a drying... The drying section dries the compressed gas; thus, the compressed gas passes through the drying section of the inner liner 2 before entering the actuator. When the gas needs to be discharged from the actuator, the solenoid valve assembly 7 is energized, and the passage between the solenoid valve assembly 7 and the constant pressure regulating section is connected; the gas through the passage causes the constant pressure regulating section to operate, thereby separating the constant pressure plug 81 from the second opening 101. The second opening 101 opens, and the return gas from the actuator will discharge the gas originally located in the drying bottle 1 and the inner liner 2, carrying out the water vapor in the inner liner 2 and extending the service life of the drying section in the inner liner 2.

[0027] Reference Figure 2 and Figure 7 The drying section consists of pressure plates 3, filter felts 4, and desiccant 5. Pressure plates 3 are installed at both the upper and lower parts of the inner liner 2. Filter felts 4 are fitted and connected to the inner sides of both pressure plates 3, and desiccant 5 is filled between the two filter felts 4. When high-pressure gas enters the inner liner 2, it passes sequentially through the pressure plates 3, filter felts 4, and desiccant 5, and then through the upper filter felts 4 and pressure plates 3. The pressure plates 3 are used to compress the desiccant 5; the filter felts 4 are mounted on the pressure plates 3 to filter impurities; and the desiccant 5 is placed between the filter felts 4 to remove moisture from the compressed air.

[0028] Reference Figures 2-4 The constant pressure regulating unit includes a cylindrical shell 802 integrally formed and connected to the drying bottle 1. The inner side of the cylindrical shell 802 is slidably sealed with a constant pressure piston 8 connected above the constant pressure plug 81. The middle part of the constant pressure piston 8 is a cylindrical body 82 with a cavity. A constant pressure spring 9 is installed in the upper cavity of the constant pressure piston 8. The passage between the solenoid valve assembly 7 and the constant pressure regulating unit is located on the lower side of the upper cover of the constant pressure piston 8. It should be noted that the upper cover of the constant pressure piston 8 is sealed to the cylindrical housing 802, and a closed cavity is formed between the lower part of the constant pressure piston 8 and the cylindrical housing 802. When the solenoid valve assembly 7 is energized, the constant pressure regulating part is connected to the first opening 21. The gas in the actuator enters the closed cavity formed between the lower part of the constant pressure piston 8 and the cylindrical housing 802 through the passage. The constant pressure piston 8 drives the constant pressure plug 81 to move upward. The constant pressure plug 81 separates from the second opening 101, so that the gas in the drying bottle 1 can be discharged from the second opening 101. On the other hand, when the solenoid valve assembly 7 is de-energized, the passage between the constant pressure regulating part and the first opening 21 is closed by the solenoid valve assembly 7. The gas in the first opening 21 cannot reach the lower part of the constant pressure piston 8 and the cylindrical housing 802 to form a sealed cavity. Through the setting of the constant pressure spring 9, the constant pressure plug 81 keeps the second opening 101 closed. When the gas pressure in the drying bottle 1 is greater than a certain limit, the gas in the drying bottle 1 exerts an upward force on the constant pressure plug 81, which compresses the constant pressure spring 9, moves the constant pressure plug 81 upward, and the gas in the drying bottle 1 is discharged. When the pressure is restored, the constant pressure spring 9 returns to its original position, and the constant pressure plug 81 continues to seal the second opening 101.

[0029] Reference Figure 2 , Figure 3 and Figure 10 A spring adjusting seat 10 that cooperates with the constant pressure spring 9 is installed on the upper part of the cylindrical housing 802. A constant pressure end cap 11 is assembled and connected to the upper side of the spring adjusting seat 10. The upper part of the constant pressure spring 9 is located in the cylindrical cavity of the spring adjusting seat 10. A component for adjusting the compression of the constant pressure spring 9 is provided between the spring adjusting seat 10 and the constant pressure end cap 11.

[0030] The lower side of the constant pressure end cap 11 is provided with a plurality of grooves of different depths. The spring adjusting seat 10 is provided with a protrusion that mates with the grooves. When the protrusion of the spring adjusting seat 10 is located in different grooves, the spring adjusting seat 10 compresses the constant pressure spring 9 to different degrees. The constant pressure end cap 11 and the spring adjusting seat 10 are fastened together. In this embodiment, by the cooperation between the spring adjusting seat 10 and the constant pressure end cap 11, the protrusion of the spring adjusting seat 10 can be located in grooves of different depths by rotating the constant pressure end cap 11. The greater the depth of the groove, the closer the spring adjusting seat 10 is to the upper constant pressure end cap 11, and the smaller the compression of the constant pressure spring 9. Thus, the compression of the constant pressure spring 9 can be changed by changing the location of the protrusion in the groove at different depths. The compression of the constant pressure spring 9 can be adjusted by coordinating different positions, thereby controlling the maximum air pressure of the air circuit. This allows the constant pressure plug 81 on the constant pressure piston 8 to be pushed after exceeding the safe air pressure, opening the pressure relief channel to release pressure and prevent exceeding the safe air pressure.

[0031] Reference Figure 3 A first sealing ring 83 connects the constant pressure end cap 11 to the cylindrical housing 802, a second sealing ring 84 connects the spring adjusting seat 10 to the constant pressure end cap 11, and a third sealing ring 85 seals the constant pressure piston 8 to the cylindrical housing 802. In this embodiment, the first sealing ring 83, the second sealing ring 84, and the third sealing ring 85 prevent external gas from entering the cylindrical housing 802 from between the constant pressure end cap 11 and the cylindrical housing 802.

[0032] Reference Figure 3 The cylindrical housing 802 has a sliding post 803 located above the second opening 101, and the lower part of the cylindrical body 82 is located inside the sliding post 803. In this embodiment, the sliding post 803 ensures that the lower part of the constant pressure piston 8 can only slide vertically relative to the sliding post 803, while also facilitating the sealing between the constant pressure piston 8 and the sliding post 803.

[0033] Reference Figure 8 The cylindrical body 82 of the constant pressure piston 8 has a through hole at its lower part, which connects the inner cavity of the cylindrical body 82 to the second opening 101. A piston sealing ring 86 is provided on the outer side of the cylindrical body 82, which is slidably sealed to the sliding column 803. The through hole at the lower part of the cylindrical body 82 is located below the piston sealing ring 86. In this embodiment, with the first sealing ring 83, the second sealing ring 84, and the third sealing ring 85 isolating the upper part of the constant pressure piston 8 from the outside gas, the through hole allows the gas in the upper part of the constant pressure piston 8 to communicate with the second opening, thereby making the gas pressure in the cylindrical housing 802 the same as atmospheric pressure. The through hole communicates with the second opening 101, allowing the gas in the sealed cavity at the upper part of the constant pressure piston 8 to communicate with the outside, preventing back pressure from forming.

[0034] Reference Figure 4 and Figure 5 The solenoid valve assembly 7 includes a solenoid valve housing 71, a coil assembly 72 inside the solenoid valve housing 71, a C-shaped frame 73 at the inner end of the coil assembly 72, a moving iron core 75 and a fixed iron core 74 inside the coil assembly 72, a spring 76 between the fixed iron core 74 and the moving iron core 75, and a sealing end 77 connected to one end of the moving iron core 75. When the coil assembly 72 is not energized, the sealing end 77 closes the passage between the constant pressure regulating part and the first opening 21. When the coil assembly 72 is energized, the sealing end 77 opens the passage between the constant pressure regulating part and the first opening 21. At the same time, the solenoid valve assembly 7 also includes a fixed iron core sealing ring 78, a first solenoid valve sealing ring 79, a second solenoid valve sealing ring 710, and a third solenoid valve sealing ring 711 located on the end face of the solenoid valve housing 71 to keep the solenoid valve assembly 7 in a sealed state.

[0035] Working principle, refer to Figures 1-10 : When the air pump is working, high-pressure gas is generated by piston compression. It enters the lower part of the desiccant bottle 1 through a one-way valve. The high-pressure gas passes through the small holes of the desiccant pressure plate 3 and the filter felt 4, and then passes through the desiccant 5 to remove moisture. Finally, it passes through the filter felt 4 and the small holes of the desiccant pressure plate 3 at the other end and enters the air outlet of the desiccant bottle 1 through the air inlet of the inner liner 2. The first quick-connect air pipe connector 14 is installed on the air outlet of the desiccant bottle 1 for connecting to an external air pipe to the air tank. Finally, the air tank supplies air to the actuator through the distribution valve. The actuator can provide air to the vehicle's air suspension, thereby lifting the vehicle. When the vehicle needs to be lowered, high-pressure gas in the vehicle's air suspension enters the desiccant bottle 1 in reverse through the first quick-connect air hose connector 14. It should be noted that the quick-connect air hose connector is a tool that allows for quick and reliable connection or disconnection of the air hose without any tools. The air hose can be easily pulled out by pressing the release ring on the connector. At this time, the solenoid valve assembly 7 is energized through the plug connected to the external wiring harness. Under the electromagnetic force of the fixed iron core 74, the moving iron core 75 overcomes the spring force of the spring 76, opening the air passage formed with the sealing end 77. When the internal air passage of the time-determining iron core 74 is closed by the passive iron core 75, high-pressure air enters the sealed chamber formed by the second solenoid valve sealing ring 710, the third solenoid valve sealing ring 711, and the moving iron core 75 through the small hole of the sealing end 77. It then enters the lower part of the constant pressure piston 8 through the small hole inside the drying bottle 1, forming a sealed chamber between the piston sealing ring 86 and the third sealing ring 85. This pushes the constant pressure piston 8 to overcome the spring force of the constant pressure spring 9 and move it upwards. The constant pressure plug 81 opens, and high-pressure gas passes through the desiccant pressure plate 3, the filter felt 4, and the desiccant 5 from the top of the drying bottle 1. The gas is discharged through the exhaust port, and then connected to the exhaust pipe through the plastic connector 15 and the second quick-connect air pipe connector 16, finally discharging the high-pressure gas. During the discharge of the high-pressure gas, the desiccant 5 passes through it, allowing the moisture in it to be discharged along with the high-pressure gas, ensuring the service life of the desiccant 5; inside the constant pressure piston chamber of the desiccant bottle 1, the upper part of the constant pressure piston 8 has a small hole that communicates with the mounting cavity of the solenoid valve assembly 7, and then communicates with the exhaust port through a small hole on the side wall of the constant pressure piston 8, preventing air pressure from hindering the movement of the moving iron core 75 and the constant pressure piston 8 when they are opened; when the solenoid valve When assembly 7 stops working, the moving iron core 75 resets, and the residual gas inside the solenoid valve assembly 7 communicates with the small hole in the mounting cavity of the solenoid valve assembly 7 through the inner hole channel of the fixed iron core 74. Finally, it is discharged through the small hole on the side wall of the constant pressure piston 8. At the same time, the spring adjusting seat 10 and the constant pressure end cover 11 are provided with adjusting bosses, which can be used to adjust the compression of the constant pressure spring 9 by different positions, thereby controlling the maximum air pressure in the air circuit. This allows the constant pressure plug 81 on the constant pressure piston 8 to be pushed after exceeding the safe air pressure, opening the pressure relief channel to release pressure and avoid exceeding the safe air pressure.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
